Question

Why is the boiling point of tertiary butyl bromide lower than n-butyl bromide?

Answer 1

Hey...
The boiling point decreases with increase in branching. This is because molecule becomes more spherical with less surface area.

As a result intermolecular forces become weaker resulting in lower boiling point.

So n-butyl bromide has high boiling point than tert-butyl bromide.
Hope this helps :)
